I killed the job and re-submit it. At this can it can go on to run, but
today I found an even serious problem with Ompi. I compared the results of
mpich2 and ompi, finding that the results from ompi is wrong, which finished
prior to the real end. In other word, the optimized structure (by vasp) does
not converge, but it reported that the run was successful. Amasing! For the
same initial structure, run with mpich2 requires 80 ion steps, while the
run with ompi needs only 40!
